'It's time': Edward Snowden just issued a cryptic warning on Twitter

Former National Security Agency contractor-turned-whistleblower Edward Snowden issued a mysterious call for former colleagues to reconnect with him on Wednesday, tweeting “It’s time” to his more than two million followers.

Snowden also quoted a tweet by journalist and author Barton Gellman, who said he is seeking information on Snowden’s work in the intelligence community so he can “tell it truthfully.”

The cryptic tweet comes less than a week after Snowden exchanged Twitter barbs with WikiLeaks. The anti-secrecy organisation implied that Snowden was trying to win the favour of Democratic presidential nominee Hillary Clinton in order to regain entry into the US.

Snowden is currently living in exile in Russia, after leaking information about the NSA’s surveillance programs in 2013. He has previously stated that his one condition for returning to the US would be the guarantee of a fair trial and the ability to argue his case before a jury against the charges he faces under the Espionage Act.
